At operation 610, the processor 360 may set up both the first screen timeout time related to the (local) display 310 of the electronic device 300, and the second timeout time related to the external display device 301 in response to a user input.

According to certain embodiments, the second screen timeout time may be longer than the first screen timeout time. For example, the first screen timeout time may be set to approximately 30 seconds to 50 seconds, and the second screen timeout time may be set to approximately 10 minutes to 15 minutes. The processor 360 may update the first screen timeout time and the second screen timeout time according to the final user input time and the occurrence of a predetermined event.

At operation 620, the processor 360 may turn on the screen of the display 310 of the electronic device 300, and the screen of the external display device 301.

At operation 630, the processor 360 may determine whether the first screen timeout time of the display 310 of the electronic device 300 has elapsed.

According to certain embodiments, when a predetermined time has elapsed from the last time of user input to the display 310 of the electronic device 300, or when a user input occurs at the external display device 301 for a predetermined time, the processor 360 may determine that the first screen timeout time has elapsed.

When the first screen timeout time has elapsed, the processor 360 may turn off the screen of the display 310 of the electronic device 300 at operation 640.

According to certain embodiments, when the first screen timeout time has not elapsed, the processor 360 may maintain both the screen of the display 310 of the electronic device 300 and the screen of the external display device 301 in a turned-on state.

At operation 650, the processor 360 may determine whether the second screen timeout time of the external display device 301 has elapsed.

When the second screen timeout time of the external display device 301 has elapsed, the processor 360 may turn off the screen of the external display device 301 at operation 660.

According to certain embodiments, when the second screen timeout time has not elapsed, the processor 360 may maintain the screen of the display 310 of the electronic device 300 in a turned-off state and also maintain the screen of the external display device 301 in a turned-on state.

According to certain embodiments, when the first screen timeout time has elapsed and also when the second screen timeout time has elapsed, the processor 360 may turn off both the screen of the display 310 of the electronic device 300 and the screen of the external display device 301 and also operate the electronic device 300 in a sleep mode.

Therefore, according to the certain embodiments, battery power consumption of the electronic device 300 can be reduced by independently controlling the power of the display 310 of the electronic device 300 and the power of the external display device 301.
